Verified step by step guidance1
Identify the central atom in the molecule CO₂, which is carbon (C).
Determine the number of regions of electron density (bonding and lone pairs) around the central carbon atom. In CO₂, carbon forms two double bonds with two oxygen atoms and has no lone pairs.
Recall that the electron geometry depends on the total number of electron regions around the central atom. Two regions of electron density correspond to a linear electron geometry.
Use the VSEPR theory principle that electron regions repel each other and arrange themselves as far apart as possible, which for two regions is 180° apart, resulting in a linear shape.
Conclude that the electron geometry around the central carbon atom in CO₂ is linear.
